Answer: In 1997, from the research project of the Ministry of Science “Research, design, fabrication of sheet metal cutters,” the scientists from the Institute of Machinery and Industrial Instruments (IMI) studied. design, manufacture of CP 2580 – CNC plate cutter using gas-plasma, automatic control. The advantage of this cutting system is that the operator can directly or indirectly program the shape of the machine.
With conventional techniques, in order to create complex shapes on steel plates with a thickness of nearly 20mm, sampling and adjustment of hand tools take up to 70% of the time of manufacture. With gas-plasma cutting machine, thanks to the pre-programmed and automatic cutting process, the cutting of parts takes only 20% of the time of product manufacture, and the accuracy of the parts is very high.
